Spotlight 4: New England and Corner Rise Seamounts [PDF]

Oceanography, 2010
One of the longest seamount tracks in the Atlantic Ocean was formed by the Great Meteor or New England hotspot. This more than 3000-km-long hotspot track formed both the New England and Corner Rise seamounts, with a pause in volcanism 83 million years ...

Pyritized tube feet in a protasterid ophiuroid from the Upper Ordovician of Kentucky, U.S.A. [PDF]

, 2006
A single specimen of the protasterid ophiuroid Protasterina flexuosa from the Kope Formation (Cincinnatian, Upper Ordovician) of Kentucky exhibits three−dimensionally pyritized tube feet. This represents the first report of soft−tissue preservation in an

Ophiodilactones A and B, Cytotoxic Tetrameric Phenylpropanoids, from the Ophiuroid Ophiocoma scolopendrina

, 2016
Two tetrameric phenylpropanoids, ophiodilactones A (1) and B (2), were isolated from the ophiuroid Ophiocoma scolopendrina. Their structures were determined on the basis of spectroscopic data. Ophiodilactone B has a novel carbon skeleton.

Benthic communities of DeepInsight Hill, Mohn’s Ridge (Arctic Ocean)

Frontiers in Marine Science
The DeepInsight Hill area on Mohn’s Ridge exhibits high biological heterogeneity associated with geological complexity ranging from fault scarps to sedimentary plains. This study applies the DeepSee object detection model alongside manual video review to

Ophiuroid ossicles from the Kallankurichchi Formation (Maastrichtian) of Ariyalur Group, Tamil Nadu, India

, 1999
This paper reports the finding of ophiuroid ossicles in the Kallankurichchi Formation (Maastrichtian) of Ariyalur Group, Tamil Nadu. The material is rather ill preserved and represents indeterminate vertebrae, dorsal shields, possible genital bars and ...

Resolving the Genetic Divergence and Population Structure in the Circumpolar Ophiuroid Ophiura sarsii Complex

Aim: The presence of cryptic species causes significant challenges to biodiversity assessment and biological resources management. Here, we investigate the genetic structure and biogeographical patterns of a complex ophiuroid species as a case study ...
